Do you get decreased or increased cardiac output in preeclampsia?

Decreased. Preeclampsia is a disorder with decreased intravascular volume (vasoconstriciton and leaky capillaries lead to third-spacing), therefore the cardiac output is accordingly decreased. In rare cases (especially with multifetal pregnancies, large mother/fetus) preeclampsia can cause peripartum cardiomyopathy which can further profoundly decrease the cardiac output.

How can an increased cardiac output help exercise?

Exercise increase CO. Exercise increases cardiac output as it usually increases both heart rate(hr) and stroke volume (sv) (amount of blood ejected by the heart in each beat) as cardiac output (co) = hr x sv. It is a compensatory mechanism to keep up with the demands of oxygen by the body doing exercise. If the cardiac output would not increase, the body would not be able to perform for long.

Why is there increased cardiac output in anemia?

Contracts harder. The cardiac output is the stroke volume times the heart rate. So the heart has to contract harder and/or faster. Typically, in severe anemia, an echocardiogram would show the heart contractng harder than normal. Read more...
Oxygen. The delivery of oxygen to the body is the product of cardiac output and the amount of oxygen per unit of blood. If the amount of oxygen per unit of blood falls, the body reacts by increasing cardiac output so that the amount of oxygen delivered to the body is maintained. Read more...
Blood volume. Plasma volume is expanded in patients with chronic anemia to compensate for the reduce red cells thus cardiac output is increase even if the heart rate is unchanged. . Read more...

Can you tell me how could an increased cardiac output help exercise?

Increase O2 delivery. During exercise, the muscles burn more oxygen for fuel. Increasing cardiac output increases the amount of oxygen carried by the blood to the tissues. Read more...

Can congenital heart defects or certain drugs result in increased cardiac output? What else causes it? Mine is 7.2lmin squared.

Yes. Medications and certain medical conditions can raise your cardiac output. But before going further, we need to know how you had your cardiac output measured, since the technique itself can give us some answers. Read more...
CO = HR x SV. Cardiac output (co) is the volume of blood pumped per minute, and related to heart rate (hr) and stroke volume (sv) (volume per heart beat). It can be affected by many bodily activities. An increase in either hr or sv can result in inceased co. So any drug that increases hr (caffeine, etc) can result in incresed co. Certain congenital heart defects (such as septal defects) can alter co. Read more...
